Page 153 highlights

Intel® Server Board S1200V3RP BIOS Setup Interface [Above 1500m](above 4920ft) Optimal performance setting at the highest elevations. Comments: This option sets an altitude value in order to choose a Fan Profile that is optimized for the air density at the current altitude at which the system is installed. Back to [System Acoustic and Performance Configuration] - [Screen Map] 3. Set Fan Profile Option Values: Performance Acoustic Help Text: [Performance] - Fan control provides primary system cooling before attempting to throttle memory. [Acoustic] - The system will favor using throttling of memory over boosting fans to cool the system if thermal thresholds are met. Comments: This option allows the user to choose a Fan Profile that is optimized for maximizing performance or for minimizing acoustic noise. When Performance is selected, the thermal conditions in the system are controlled by raising fan speed when necessary to raise cooling performance. This provides cooling without impacting system performance but may impact system acoustic performance - fans running faster are typically louder. When Acoustic is selected, then rather than increasing fan speed for additional cooling, the system will attempt first to control thermal conditions by throttling memory to reduce heat production. This regulates the system's thermal condition without changing the acoustic performance but throttling memory may impact system performance. Back to [System Acoustic and Performance Configuration] - [Screen Map] 4. Fan PWM Offset Option Values: [Entry Field 0 - 100, 0 is default] Help Text: Valid Offset 0 - 100.This number is added to the calculated PWM value to increase Fan Speed. Comments: This is a percentage by which the calculated fan speed will be increased. The user can apply positive offsets that result in increasing the minimum fan speeds.
